After adopting the above scheme, when the screening disc 3 moves back and forth, it will drive the guide rod 331 to move along the through hole 231, which is used to guide the screening disc 3. At the same time, the guide member 23 also supports the guide rod 331 to achieve a supporting effect on the screening disc 3, thereby ensuring the stability of the screening disc 3.

[0045] Optionally, by Figure 1-Figure 4As shown, in this embodiment, a No. 2 fixing ear 34 is fixed at the end of the frame 31, and a pull rod 341 is fixed on the No. 2 fixing ear 34, the power mechanism 4 includes: a driving motor 41, a rotating arm 42 and a swing arm 43, the driving motor 41 is fixed on the mobile base 1, the rotating arm 42 is fixed on the output shaft of the driving motor 41, the pull rod 341 passes through one end of the swing arm 43 to form a rotating structure, and the other end of the swing arm 43 is connected to the free end of the rotating arm 42 to form a rotating structure.

The No. 3 fixing ear 44 is fixed to the top surface of the mobile base 1, and one end of the auxiliary arm 45 is connected to the No. 3 fixing ear 44 by a fixed shaft 451 to form a rotating structure. The threaded rod 46 passes through the rotating arm 42, the swing arm 43 and the auxiliary arm 45, and locking nuts 47 are installed on both ends of the threaded rod 46 by threaded engagement. After adopting the above scheme, the auxiliary arm 45 is located on the opposite side of the rotating arm 42 and is distributed parallel to the rotating arm 42. The auxiliary arm 45 is supported by the No. 3 fixing ear 44 and is connected to the No. 3 fixing ear 44 by a fixed shaft 451 to form a rotating structure, and the rotating arm 42 and the auxiliary arm 45 are connected to the swing arm 43 by a threaded rod 46 to form a rotating structure.

[0052] Example 2

[0053] Please refer to Figure 1 and Figure 4 In the present embodiment, another screening disc 3 is fixed on the top of the screening disc 3, and the assembly of different screening discs 3 can be carried out by conventional means such as bolts. It is also worth noting that, as can be clearly seen from the figure, the mesh sizes of the two screening discs 3 are different, and the directions of the coarse material discharge ports 311 of the two screening discs 3 are opposite. More specifically, the mesh diameter of the screening disc 3 located above is larger. That is to say, in actual use, if necessary, a screening disc 3 with a larger mesh can be fixed on the top of the screening disc 3, and the directions of the coarse material discharge ports 311 of the two screening discs 3 are opposite (it can also be other directional relationships, as long as they are in different directions). At this time, the screening equipment can achieve more levels of screening.

[0054] It should be noted that the drive motor 41 is a conventional device purchased on the market with a built-in power switch. Technicians in this field can make a conventional selection according to usage requirements. Its working principle is common knowledge known to technicians in this field and has been fully disclosed in the prior art, so it will not be elaborated in this article.

[0056] Components not described in detail herein are prior art.

[0057] Working principle and use process of the present invention: When the screening device of the present invention is used, the screening and recovery device is first moved to the working place, and then the driving motor 41 is started to drive the rotating arm 42 to rotate, and the free end of the rotating arm 42 makes a circular motion, and at the same time drives the swing arm 43 to swing and move back and forth, and the swing arm 43 and the pull rod 341 drive the screening plate 3 to move back and forth to achieve the shaking effect;

[0058] The waste building materials to be screened are put into the frame 31 from the higher end of the porous screen plate 32. The frame 31 drives the porous screen plate 32 to reciprocate to screen the waste building materials. Smaller particles pass through the mesh of the porous screen plate 32, then fall into the fine material guide trough 2 and roll down along the inclined surface of the guide bottom plate 21. Larger particles roll down along the inclined direction of the porous screen plate 32 and are finally discharged from the coarse material discharge port 311 to achieve screening.

[0059] The present invention drives the screening plate 3 to reciprocate to achieve an oscillating effect through the power mechanism 4 provided, and is used to screen the building material waste. The screening device of the present invention adopts a skid-mounted structure and has walking wheels 11, which is convenient for overall movement and is suitable for turnover and use within the construction site.
